This paper presents the modeling and simulation of power loads due to plug-in electric vehicles' (EVs) charging events at a dc fast charging station. Two algorithms for modeling the loads are introduced and compared, one based on sampling and one based on statistical distribution built from the sample database. Simulation of load versus time was performed using a horizon of 7 days using both techniques. The cause for the difference in the result of these two approaches is explored. Regardless of the method used, the results show that a dc fast charging station with 6 fast chargers potentially serving 700 plugin EVs generally gets 105 charging events per day with a peak load of 375 kW.
